is removed as indicated at 43 to form an opening of greater width than the distance between the contact points. When the sheets are assembled, the fasteners are arranged to inclose the upper flanges of the rafters and the seam 323334 and are driven downwardly at an angle to the rafters, whereby the sheets are rlgidly held to the rafters and the several roof sheets are firmly clamped together along the seams. The fasteners 40 are punchii'igs and are, therefore, cheap.

The side edges of the roofing sheets are best shown in Figs. 2 and 5, from which it will be seen that the material is cut away opposite the portions 31- 32, 3435, and that between these points the sheet is bent upwardly about the thickness of the metal and then back upon the body portion at 45. The element 45 is turned over into the position shownbefore the element 34 is bent down over the body portion. The roofing sheets being assembled, key plates 46 (having downturned lower edges of the same configuration-as the edges 31-32 of the roofing plates and having down and inturned marginal flanges 49) are driven upwardly into locking position, as indicated in Fig. 2. The ends of adjacent ridge boards and cave sheets are formed and joined in the same general manner, and the same reference numerals have been applied thereto. The seams are arranged above the rafters throughout.

The end roof sheets 55 (Fig. 2) and the end ridge plates 55 (Fig. 9) differ from the intermediate plates in that they are provided with downturned marginal flanges 56 and 5? that fit closely to the outer edges of plates 28 of the end gables, whereby light, air and moisture are excluded.

The construction is exceedingly light (for example, in hospitals, twenty feet in width and with the trusses four feet apart, the weight of the trusses need not exceed one hundred pounds) and cheap, may be nested and transported in a relatively small space,

and may e assembled rapidly and without the use of skilled labor.

While the fasteners have been shown only for attaching roofing plates to rafters, it is clear that they may also be employed to secure overlapping sheet metal plates to studding and other supports for the purpose of forming vertical walls or other structural panels, and for lack of a more generic term panels has been employed in some of the claims. It will be observed that the fastoners are located on the side of the sheet metal plates next the supports and are partly pocketed in the space between the overlapping portion of the outer plate and the seam by which upper and lower plates are joined.

The details of construction may be varied considerably in other particulars; and I do not, therefore, wish to be limited otherwise than as indicated by the subjoined claims.

I claim:

1. A roof comprising a lurality of columns and a plurality of roof trusses cor responding to the columns, each of the roof trusses having a thin metal extension projecting beyond the columns to form an cave plate support and retainer, roof plates and 1 save plates resting on the trusses, said roof plates overlapping the eave plates and being interlocked therewith, said eave plates extending out over the extensions and having their edges turned downwardly and inwardly beneath the extensions, whereby the cave plates and roof plates are retained in position on the trusses.

2. Means for forming structural panels comprising supporting means and upper and lower rows of sheet metal plates secured thereto, each of the plates including a lower edge turned back upon and spaced from the body thereof on the side next the supporting means and an upper edge turned back upon and spaced from the body thereof on the side opposite the support to form a groove in which the lower edge of the sheet next above is received, each of said plates also including side edges turned back upon the body and spaced therefrom on the side opposite the-supports, said turned back side edges terminating at substantially the beginning of the turned back lower edge of the corresponding plate, and sheet metal key plates for connecting the adjacent plates of each row, each of .said key plates having their lower edges bent back upon themselves and spaced from the bodies thereof on the side next the supporting means to corre spond to the lower edges of the sheet metal plates of the corresponding row, and their side edges turned back upon and spaced from the bodies thereof on'the side next the supporting means to form grooves in which the edges of the first mentioned plates are received when the key plates are forced upwardlv on the other plates.

3. Means for forming structural panels comprising supporting means and upper and lower rows of sheet metal plates secured thereto, each of the plates including a lower edge turned back upon the body thereof on the side next the supporting means, each of said plates also including side edges turned back upon the body and spaced therefrom on the side opposite the supports, said turned back side edges terminating at substantially the beginning of the turned back lower edge of the corresponding plate. and sheet metal key plates having their lower edge bent back upon themselves and spaced from the bodies thereof on the side next the supporting means to correspond to the lower edges of the first mentioned sheet metal plates. and their side edges turned back upon and spaced from the bodies thereof on the side next the supporting means to form grooves in which. the edges of the first men tioned plates are received when the key plates are forced upwardly on the other plates of the corresponding row.

4. root construction comprising a sheet metal ,u'nble end having,- a flange in the plane '01 the roof, a roof truss, a light sealing plate secured to the flange of the gable end and projecting th refrom on the side opposite the root truss. and sheet metal roof plates being spared Farther vertically from the flange of the gable end at some points along the latter than at others, said root plates including ilownturned end flanges that extend over the outer edge of the light. sealiuu' plate in close relation thereto.

.3. A. roof structure comprising a pair of metal columns and a metal roof truss ex tending across between the columns and re tingr thereon, said roof truss lltlvlng' at one end a thin metal extension. iroieetinn' beyond the (OITQSPOfidlHg column to form :1. support and retainer for a. plate whereby a partof the roof structure is formed. and. a. roolinp' plate extending out over the tension. and having its outer edge intercugaged with the extension whereby the plate is prevented from being blown up oil from the roof.

6. A roofronstruetion comprising a sheet. metal gable end having a flange inclined to conform to the opl'iosite sides of the roof. a roof truss. a light sealing plate secured to the flange of the gable end and projecting therefrom on the side opposite the roof truss, and a sheet metal ridge hoard having inclined sides corresponding to the sides of the roof, said ridge board being spaced farther vertically from the flange of the gable end at some (points alon the latter than at others an having ownwardly edges.

8.'A roof comprising rafters and a rod." striurture, the latter including a plural of upper and lower rows of sheet m ta plates the side edges and the upper edge in each of which is turned back upon the bod of the corresponding plate and spaced there l'rom on the side opposite the rafters, tli bodies of the plates extending across hetw en the rafters corresponding thereto and resting directly on said rafters. the lower edges of each of said plates being turned hark upon the liody of the corresponding plate on the side next the rafters and being tit received beneath the upper edges of thtplates of the row next. above. and, a ser ee of narrow key plates having side eds turned thereon on the side next the m L and embracing the side edges of the l iaeeut plates. the lower ends of said in plates conforming to the downturued lent-z; edges of the corresponding plates Whirl: tht-v connect.

In testim my whereof I sign this sp e fication. I
